Abstract
An air-floating thin film bonding apparatus and its air-floating roller is provided. The apparatus is composed of an air-floating rollers, which can blow out airflow at a specific angle to be applied to the base film with three-dimensional obstacles. The positive pressure provided by the airflow can be utilized to fill the gap space caused by the three-dimensional obstacles. Therefore, the base film can bond to the bonding film tightly to overcome the wrinkles and defects caused by the three-dimensional obstacle and the problem of unflatness of the film-bonding can be solved.
